Hello World for Zephyr with lvgl (8+) using the PineTime board - current example?

[lcj]

I am trying to get a working example of Zephyr with lvgl (8+) using the PineTime board. There seems to be a lot of changes since the samples I've seen. For example most of the examples have:

struct device *display_dev;
lv_obj_t *hello_world_label;

display_dev = device_get_binding(CONFIG_LVGL_DISPLAY_DEV_NAME);

if (display_dev == NULL) {
printk("Display not found.");
return;
}

hello_world_label = lv_label_create(lv_scr_act());
lv_label_set_text(hello_world_label, "Hello World");
lv_obj_align(hello_world_label, LV_ALIGN_CENTER, 0, 0);
display_blanking_off(display_dev);
lv_task_handler();

With this in the prj.conf:

CONFIG_LVGL_DISPLAY_DEV_NAME="DISPLAY"

However there seem to be changes in lvgl and Zephyr calls seem to use the devicetree, like:

const struct gpio_dt_spec display_spec = GPIO_DT_SPEC_GET_OR(DT_ALIAS(led2), gpios, {0});

Is there a more up to date "hello world" for Zephyr, PineTime, and lvgl?

Hi,

There is an up to date 'Hello World' sample for lvgl in Zephyr, the LittlevGL Basic Sample. The source code can be found in zephyr/samples/subsys/display/lvgl.

Best regards,
Marte
